Oil Additives

[oasis]

Thanks.

All of my past cars reached six digits faithfully without any additives -- just good, solid routine service. I was looking for something to clean my driveway and just saw all sorts of product for gas additives (which I didn't ask about) and oil additives.

I just didn't want to be a dunderhead and say, "I never used it so I automatically know I don't need it." (There's a guy on another forum who insists drum brakes are just as good as disks in performance situations. I felt I better ask about this before I place myself in his category.)
